Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our quarterly income tax (provision) benefit for income taxes is measured using an estimated annual effective tax rate for the period, adjusted for discrete items that occurred within the periods presented. For the three months ended March 31, 2012, we recorded an income tax benefit of $1.2 million, which represents an effective tax rate of (2.1)%. The effective tax rate for the three months ended March 31, 2012 differs from the federal statutory rate of 35.0% primarily due to changes in recorded valuation allowances, the impact of state income taxes and changes in deferred tax liabilities related to the stock basis of subsidiaries. The Debt Repurchases resulted in a tax gain of $69.8 million for the three months ended March 31, 2012. Generally, the discharge of a debt obligation for an amount less than the adjusted issue price creates cancellation of debt income ("CODI"), which must be included in the taxpayer's taxable income. However, in accordance with Internal Revenue Code ("IRC") Section 108, in lieu of recognizing taxable income from CODI, the Company is required to reduce existing tax attributes. As a result, the Company recognized an estimated decrease in deferred tax assets relating to net operating losses and the basis of amortizable and depreciable property of approximately $27.2 million. These decreases were offset by a decrease in recorded valuation allowance during the three months ended March 31, 2012. The estimated annual effective tax rate for the current year includes an estimate of the change in the valuation allowance expected to be necessary at the end of the year. The Company also recorded a decrease in the valuation allowance during the three months ended March 31, 2012 as a result of the Debt Repurchases (discussed above). In addition, the valuation allowance was decreased during the three months ended March 31, 2012 as a result of the reduction in estimated useful lives of certain intangible assets as discussed in Note 2, "Summary of Significant Accounting Policies - Identifiable Intangible Assets," which was a change in circumstances that resulted in a change in judgment about the Company's ability to realize deferred tax assets in future years. The resulting decrease in income tax expense allocated to the three months ended March 31, 2012 relating to the changes in valuation allowance is $25.6 million, which reduces the effective tax rate for the three months ended March 31, 2012 by approximately 45.5%. For the three months ended March 31, 2011, we recorded an income tax (provision) of $(20.2) million, which represents an effective tax rate of 26.8%. The effective tax rate for the three months ended March 31, 2011 differs from the federal statutory rate of 35.0% primarily due to changes in deferred tax liabilities related to the stock basis of subsidiaries, the impact of state income taxes and a valuation allowance that has been recorded. Upon emergence from bankruptcy, where required pursuant to FASB ASC 740-30-25-7, Income Taxes, the Company recorded deferred tax liabilities related to the excess of the financial statement carrying amount over the tax basis of investments in certain subsidiaries. The estimated annual effective tax rate for the current year includes an estimate of the change in these deferred tax liabilities for the year. The resulting reduction in income tax expense allocated to the three months ended March 31, 2011 relating to the change in these deferred tax liabilities is $6.4 million, which reduced the effective tax rate for the three months ended March 31, 2011 by approximately 8.4%.
